I'd say that was a pretty inaccurate summary personally.
Have a look at a 2600 review from the other week: http://www.tomshardware.co.uk/the-radeon-2600xt-remixed,review-29624-11.html
It's pretty much on a par with the GeForce 8600GT.
I believe you're not a gamer or never had a good gfx card on your hands...
Does that review card have the clocks we have on the mac? No 600Mhz GPU mac version VS 800Mhz GPU (memory is close enough).
Did you see any test above 1600x1200? No
Where do you see the card getting good fps? 2 year old games!
Can you play below 25-30 fps? No (unless you like slide shows)
And for being on par with the 8600GT... What do I care? The 8600GT is a lame ass gaming card also.
Thank you for supporting my idea with your post
